Letters Patent No. 93,248, dated August 3, 1869.

IMPROVEMENT IN BASE-BURNERS.

The Schedule referred to in these Letters Patent: and making part of the same.

To whom it may concer-n':

Be it known that I, WILLIAM B. TREADWELL, of the city and county of Albany, and State of New York, have invented a new and useful Improvement in Stoves for Heating-Purposes; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, makinga part of this specification, the same letters always marking the same part of the stove.

My improved stove is organized and constructed with a view of giving an enlarged radiating and illuminating-surface in its front, having in its lateral front revertible fines, so locatedas to add largely to both its illuminating and radiating-surface, as represented by the elevation given by fig. l of the drawings.

Although constructed as a revertible-flue stove, it can be converted to a direct-draught stove, at pleasure, by means of the damper h, fig. 2.

This stove is organized and constructed as a baseburning or magazine revertible-fiue stove, in which the products of combustion may pass up around the magazine, or they may descend into the base of the stove, through the revertible flues K K, Figure 4, and thence out, through the back pipe L, to the chimney.

The appearance and structure of the stove are fully represented by the accompanying drawings.

Figure 1 is a representation of a front elevation of the stove, showing the various sections, as indicated by the letters at the right side of the figure, thus:

0, the cover ;v

S, the top plate;

0, the magazine-section;

B, the fire-chamber, or combustion-section;

A, the ash-pit section; and

N M N, the hot-air or base-flue section.

The illuminating-openings are seen in iiont, at c b c the arrows at in the openings at the side front, indicating the direction of the draught in the revertible flu'es; and the operation of the gases around the feed-cylinder is indicated by arrows e. 1

Figure 2 is avertical section of the stove, showing the internal organization andfs'tructure of the same; showing the magazine I, with its dissipating-tube J the chamber between the magazine and the outc'r casing of the stove; the combustion-chamber B; the ventilation-chamber H; the fire-grate D; the ash-pitand' and fines in the base of the stove M and N, and the exit-pipe L.

Figure 3 is a horizontal section of the stove, taken at the red line aJ-x, in fig. 2, showing the outer casing of the stove O; the structure'of the magazine, with its dissipating-tube J, and the chamber of the magazine I.

Figure 4 is a representation of a horizontal section of the stove, taken on the red line xx-x x, fig. 2, showing the form of the front of the stove, with its fire-pot E, F, 850., its reveitible-flue passages K K, revertibleflue plates or. 'n n, and the escape-pipe, or exit-pipe L.

Figure 5- O is the top cover;

v W is a shank, which projects a little from the outer edge-of said cover;

P is a hall formed upon the end of said shank;

S is the top of the stove; and

m m is a concave, or socket into which the ball I? is made'to fit.

The centre of the ball and socket is cleft, to receive a bolt, k.

A nut, l, upon the end of the bolt k, with a rivet, j,

holds the parts firmly, and thus forms a ball-and-socket attached to theback of the stove, over which it can be made to rise and fall in front, similar to the swinging of the, same up and down by means of a hinge.

It is attached to the magazine in front by means of a female key-plate, with an opening in the same, attached to the portable mouth.

The male portion of the key is attachedto the front plate of the stove, so that the same passing through the opening in the female plate, by means of a lever, swinging around under the key-plate, locks the portable mouth, and holds firmly to the magazine.

By this arrangement, the fire-proof mouth is made portable, and can be attachedor detached at pleasure.

For the purpose of aiding in the consumption of the.

gases, an air-chamber is formedin the back of the stove, at H, fig. 2, by means of which air, more or less heated, is admitted into the fire or combustion-chamber, through the perforated plate, separating the same from the air-chamber H.

Having thus fully described my said improvement, I will proceed to state what I claim as my invention, and'desire to secure by Letters Patent.

1. I claim the construction and arrangement of the front of my combustion-chamber and revcrtible flues, in such a manner, relatively, as to increase the radiation and illuminating-surface'of the front of the stove, in the manner set forth and described.

, 2. I claim my portable mouth to my magazine, in combination withthe enlarged mica door, or opening chamber, feed-cylinder, portable mouth, and revertible flues, substantially as described.

6. I claim, the air-chamber H, in combination with my combustion-chamber and revertible flues, substantially as described.
